Just running a new version of twsearch and found what I think is a new adjacent double-parity algorithm for the 4x4x4; it's only 17QTM.

2F 2F 2L' 2F' U R U D L' 2U' L U' D' R' U' 2F' 2L

I make no claim this is particularly useful for speedsolving, but the algorithm itself is kind of cute.

For completeness, here are all optimal 17-move slice quarter-move solutions to this position:

Code:
 2F 2F 2L' 2F' U R U D L' 2U' L U' D' R' U' 2F' 2L
 2F 2L' U' B' U' D' F 2U' F' U D B U 2L' 2F' 2L 2L
 2B 2B 2R 2B U R U D L' 2D L U' D' R' U' 2B 2R'
 2B' 2R U' B' U' D' F 2D F' U D B U 2R 2B 2R 2R
and here are all optimal 16-move slice half-move solutions to this position:

Code:
 2F 2L' U' B' U' D' F 2U' F' U D B U 2L' 2F' 2L2
 2F2 2L 2F' U2 L2 U' R' L' 2D' R L U L2 U2 2F' 2L'
 2F2 2L' 2F' U R U D L' 2U' L U' D' R' U' 2F' 2L
 2F' 2L' U2 F2 U B F 2D' B' F' U' F2 U2 2L' 2F 2L2
 2B 2R U2 F2 U B F 2U B' F' U' F2 U2 2R 2B' 2R2
 2B2 2R 2B U R U D L' 2D L U' D' R' U' 2B 2R'
 2B2 2R' 2B U2 L2 U' R' L' 2U R L U L2 U2 2B 2R
 2B' 2R U' B' U' D' F 2D F' U D B U 2R 2B 2R2
 2L 2F U2 L2 U R' L' 2D R L U' L2 U2 2F 2L' 2F2
 2L2 2F' 2L U2 F2 U' B F 2D B' F' U F2 U2 2L 2F
 2R2 2B 2R' U2 F2 U' B F 2U' B' F' U F2 U2 2R' 2B'
 2R' 2B' U2 L2 U R' L' 2U' R L U' L2 U2 2B' 2R 2B2

Here's some optimal-in-a-blended-metric ones for checkerboard-in-opposite-dedges.
Only 13 QTM.

2L' 2F 2L' U2 s' 2L' s U2 2L' 2F' 2L'

Code:
2L' 2F 2L' U2 s' 2L' s U2 2L' 2F' 2L'
2L' 2F' 2L' U2 s 2L' s' U2 2L' 2F 2L'
2L' 2B 2L' U2 s 2L' s' U2 2L' 2B' 2L'
2L' 2B' 2L' U2 s' 2L' s U2 2L' 2B 2L'
2R' 2F 2R' U2 s' 2R' s U2 2R' 2F' 2R'
2R' 2F' 2R' U2 s 2R' s' U2 2R' 2F 2R'
2R' 2B 2R' U2 s 2R' s' U2 2R' 2B' 2R'

OLL/PLL algorithm discovered using Bidirectional BFS.
These algorithm are "optimal moves"(QTM). They consist of RR'LL'UU'DD'FF'BB' only, and all ending with R/R'.
Most of these need human processing (inserting some xyz moves for example) to be practical to use.

1LLL / pure OLL I guess:
r U' r' S' r' U r2 S' U r' S r' U' R

(I had this in a Notepad++ tab and I forgot what I was doing with it.)

edit: The mirror r' U r S' r U' r2 S' U' r S r U R' actually seems… good? Definitely faster than doing the normal OLL into a Z perm.

Some ELL + PLL parity case

2R U 2R' U' 2R' U' 2R U 2R U' 2R' U' 2R' U 2R
(also works if you invert the directions of all the 2R moves, or of all the U moves, or of all the moves, thanks to the layer-swapping automorphisms)

Alternatives(?):
2R2 U2 2R2 u2 2R2 u2 M' U M2 U M U2 M' U M' (opp swap into normal ELL)
r2 B2 r2 b2 2R2 b2 M' U M2 U R2 B2 R2 U' M' (lots of left hand regrips)
x' r2 U2 r2 u2 2R2 u2 M' F M2 F R2 U2 R2 F' M' (x) (or a single initial regrip with lots of F moves)
3r U R' U 2R2 U2 2R2 u2 2R2 u2 U R U' R' U M (set up to adj swap)

(Awesome new algs!)
I added them to this section of the wiki. (There were 4 duplicates, FYI.)

I had to also update this table/section in the wiki too. (Adjacent double parity used to be the number 1 rank -- for the worst case!) And it's interesting that these algs are also 22 OBTM (like my 23,16). When I saw @qwr 's thread, about his 1.5 half turn metric idea, I remembered my move count ranking system (this table)!

Is the adjacent checkerboard next?:cool:
